Packet transmission for overlapped offset QAM

Offset Quadrature Amplitude Modulation (OQAM) presents several advantages for single carrier and multicarrier transmission when combined with OFDM. However, as the transmitted pulse shapes have an offset and overlap together this may be detrimental for the transmission of frames with very short length. In this paper we show that, under certain conditions, a slight modification of the demodulation process permits a total recovery of the high spectral efficiency these systems can attain when there is no framing constraint.
